South Korea is considering new market maker regulations after JPYC stablecoin traded at 4x its peg on Upbit, exposing liquidity and price stability issues.

A Japanese yen-backed stablecoin traded at four times its peg on Upbit, South Korea's dominant exchange, prompting regulators to consider new market maker rules. The incident exposed gaps in liquidity management and price stability mechanisms on the platform, raising broader questions about oversight of assets listed on exchanges that command outsized influence over global crypto prices.
South Korea's crypto market is concentrated among a small number of major platforms, with Upbit and Bithumb handling the bulk of domestic trading volume. This concentration means that listing and operational decisions on these exchanges carry weight beyond the country's borders, and operational failures or market distortions can cascade into broader market effects. The stablecoin price collapse illustrates how thin or absent liquidity for certain assets can create extreme slippage and expose traders to unexpected losses.
Regulatory interest in market maker standards remains nascent. The details of any forthcoming rules—including scope, compliance timelines, and penalties—have not yet been clarified. It is unclear whether the focus will be on exchange-enforced liquidity minimums, third-party market maker licensing, or wider circuit breaker mechanisms already being explored elsewhere in the region.
